地下车站分段抗浮措施探讨

同一个地下车站，因结构形式、覆土厚度、地质奈件、水位埋深等不同，可以分段采用不同的抗浮措施，包括底板下设拉锚、底板设泄水盲管、围护结构上设压顶梁、增加自重、增加压重等，以达到最佳的效果。文中就深圳地铁5号线太安站采用的分段抗浮措施进行了探讨。

Study on Anti-floating Measures in Sections of Metro Station

Due to the difference of the structure types,the thickness of cover clay,geological conditions,the depth of water level of the same metro station,the different anti-floating measures such as set up cat-anchor under bottom plate,install blind drain in bottom plate,put up capping beam on exterior protected construction,increase dead load,add weight,and etc.can be used in sections in order to achieve the optional effect.The anti-floating measures in sections used at the Taian station of Shenzhen metro line No....
